how do we know light is the fastest thing

what if there's some some secret particle that we haven't discovered yet that goes faster than light

      Please delete this. I was on the train and when I saw this I had to start furiously jerking off. Everyone else gave me strange looks and were saying things like “what the frick” and “call the police”. I dropped my phone and everyone around me saw this image. Now there is a whole train of men jerking off together at this one sentence. This is all your fault, you could have prevented this if you had just hesitated to press the post button.

        if you were fast like me nobody would have noticed

    Could be. We just need to build many slightly incrementally larger particle accelerators until we find it

    97% of the observable universe is moving away from us at FTL speeds

      >moving away
      no, nothing is "movin": it's the distance itself that is increasing. It's spacetime itself that is dilating or expanding, the celestial objects themselves aren't, in other words, they have no speed relative to us. That's why this whole thing is baffling and hard to understand.

    Its not about light, never was. C is speed of casuality, light just happen to move at that speed. In this Universe either you have mass and are below that speed or you are massless and right at it and cannot go any slower.

      All praise C the speed of our lord C. His C-ness exceeds all others. We know this to be true because the holy science man doth sayeth so. And so it was.

        it's c actually. C represents Coulomb measurement unit.

    What happens if one was to induce superluminal acoustic waves (group velocity) in a vehicle exhaust?

    Wave function collapse is faster than light but not instant.

      how is it not instant?

    Particles arent real. I cant see them, hence they dont exist. Also they do not thknk, therefore they are not am

    well, as far as we can tell and have tested, the collapse of entangled particles takes place faster than the speed of light, no matter how distant the particles are.
    We don't know or understand the fundamental why and how though. Nature, always full of mysteries!

    because effect can't happen before cause and as you get to the speed of light time slows

    holy shit a particle just flew over my house at light speed

    Empirically we have never seen anything bearing energy/information faster than light. The reason theoritically we don't think there exists a particle (usually called Tachyons) that moves at superluminal speeds comes from a philosophical principle (relativity) that states that one cannot use the Laws of Physics to tell what kind of inertial reference frame you're in. This means if Tachyons existed, we expect people living on Tachyons to experience life as if they were on a motionless body. This is not the case as light is a wave one could easily tell if they were on a Tachyon by using a flashlight and observing the equivilent of a sonic boom for light (Cherenkov Radition) .

      The frequency of basic spelling mistakes combined with the fact you took it seriously when someone acted as if what you said was AI generated is fricking mind boggling

    Einstein is a gay and light doesn't have a constant speed.

    If a particle moved faster than light, it would have the potential to interfere with causality assuming that Einstein‘s theory of special relativity is correct, for which we have much experimental proof. Nevertheless physicist do look for such particles at CERN for example. They’re called Tachyons, but so far no such particle has been discovered.

    there can't be. everything moves at c through spacetime
